Why the study?
Does environmental surveillance combined with AFP surveillance improve the completeness and timeliness of wild poliovirus detection compared to AFP surveillance alone in Pakistan?
Population
1,127 wild poliovirus (WPV) isolates detected in Pakistan from January 2011 through December 2013
Comparison
Environmental surveillance combined with acute… vs Acute flaccid paralysis (AFP) surveillance alone

ES may enable earlier, more sensitive WPV detection in endemic settings; leaves open optimal ES expansion for eradication.
Does environmental surveillance combined with AFP surveillance improve the completeness and timeliness of wild poliovirus detection compared to AFP surveillance alone in Pakistan?
Environmental surveillance provides earlier and more sensitive detection of wild polioviruses than acute flaccid paralysis surveillance alone, supporting its use in eradication strategies.
